Mean Time to Repair

Mean Time To Repair (MTTR) is the time needed to fix a failed component or module. In an operational system, repair always means upgrading a failed component or device. MTTR could  be seen as mean time for you to replace a failed equipment module. Taking a long time to repair an item drives up the price of the installation over time, due to down time before the new part arrives in addition to possible window of the time expected to schedule the installation. To avoid MTTR, a lot of companies purchase spare products in order for an alternative could be installed quickly.
